Ryan Seacrest Explains How This Season of 'American Idol' Will Be Different

Ryan Seacrest details the biggest change, calling it "exciting."

Seacrest said, however, that the combined shows won't happen until later in the competition.

"When we get to the final stage, y'know, the top 10, there'll be one night of performance and results all in one," he explained.

Seacrest also spoke enthusiastically about the new face who'll be joining the "Idol" team come January: Scott Borchetta, the head of Taylor Swift's record label, Big Machine. Borchetta's replacing longtime "Idol" fixture Randy Jackson as the show's in-house mentor.

"Clearly, when you look at Scott's track record, look at all the people he's worked with, including one Taylor Swift, and I think he'll be the perfect fit for our show," Seacrest said. "I think it'll be great."

Ratings for “Idol” have steadily declined from record highs in the early years. Last year, ratings dramatically dipped, with the average viewership for the season slipping below 20 million for the first time in a decade.
